摘　　要：目的探讨640层CT血管成像在缺血性脑血管病中的临床意义。方法选取2010年8月至2011年7月,哈尔滨市第一医院神经内科住院患者31例,使用东芝Aquilion ONE 320排640层动态容积CT进行头颈CTA扫描。结果前循环动脉血管狭窄检出率为40.32%,后循环动脉血管狭窄检出率为39.35%。CTA血管狭窄检出率明显高于磁共振血管成像、经颅多普勒和彩超。结论 320排640层动态容积CTA可以作为检查缺血性脑血管病患者颅内、颅外血管狭窄的可靠方法之一。Objective To report initial clinical experience with a 640 slice CT scanner in patients with ischemic cerebrovascular disease.Methods Thirty-one patients with ischemic cerebrovascular disease ,admitted in hospital in neurological department from August 2010 to July 2011, were performed for cervicocranial CT angiography （CTA）with Toshiba Aquilion ONE 640-slice dynamic volume CT.Rseults The frequency of anterior circulation artery stenosis was higher than that of posterior circulation artery stenosis in ischemic cerebrovascular disease patients （P=0.021）.The artery stenosis detection rate of CTA was higher than that of magnetic resonance angiography （MRA）,transcranial Doppler sonography （TCD） and ultrasound （P=0.001, P=0.000 and P=0.191 respectively）. Conclusion The results indicate 640-slice CTA as a reliable method can clearly demonstrate extracranial and intracranial artery stenosis in patients with ischemic cerebrovascular disease.
